I bought this to help boost my thyroid function. Although tests ordered by my doctor did not indicate any problem, a number of factors, plus results from basal temperature measurements, convinced me that I was dealing with hypothyroidism as I pass through menopause. After using this product for about two weeks as directed on the bottle, I have noticed a definite increase in energy and stamina. And it's much less costly than prescriptions, even with health insurance. So far, so good!
